An artillery shell weighing 10 kg flies at the target at a speed of 810 m / s. What is its kinetic energy?
August 27, 2021 | education
| The kinetic energy of a material point Eк, J, moving translationally, can be determined by the formula:
Eк = m * v ^ 2/2,
where m is the mass of the point, kg;
v – point speed, m / s.
Then, for the case under consideration, we have:
Eк = 10 * 810 ^ 2/2 = 3280500 J ≈ 3.28 MJ.
